A dilution refrigerator, such as for a quantum computing system, includes a cryostat having a plurality of temperature-controlled flanges inside a vacuum chamber. A dilution unit is disposed inside the cryostat and operable to cool a first group of the flanges. A continuous flow helium refrigerator is in heat transfer communication with a lowest temperature flange of a second group of flanges, disposed at progressively lower temperatures that are greater than those of the first group of flanges, to provide primary cooling thereto to a first temperature. The continuous flow helium refrigerator resides at least partially in the cryostat and includes a helium liquefier and a first closed-loop circuit thermally coupling the helium liquefier to the lowest temperature flange of the second group of flanges. The helium liquefier provides liquid helium to the lowest temperature flange of the second group of flanges via the first closed-loop circuit.

An acoustic damper includes a low porosity layer section and a housing. The low porosity layer section is formed in a liner of a gas turbine combustor and has an arrangement of elongated generally S-shaped slots formed therein. The housing has a plurality of feed apertures. The housing is coupled to the low porosity layer section thereby defining a cavity such that air outside the housing is configured to flow through the apertures and through the elongated generally S-shaped slots in the low porosity layer section, thereby transforming acoustic energy into thermal energy and aiding in providing an acoustic dampening effect for the gas turbine combustor during operation thereof.
